The conditions under which an input signal is used as
the trigger to start recording are:

• when recording digitally, a digital start signal is

detected, and audio is subsequently detected

or

• the sound level rises above the threshold (see

below) after having been below the threshold for
one second or more. Note that the diagram below
represents a special case (the source is stopped or
paused) of the more general condition, as explained
later:

To start synchronized recording when the source is
stopped or in pause mode:

1

Place the unit in record ready mode, with the

SYNC

indicator in the display lit, as explained

above.

2

Start playing the source. The pause indicator
disappears from the display, and the unit
starts recording.

The conditions under which synchronized recording
stops are:

• when recording digitally, an appropriate digital sig-

nal is detected. If the signal is detected from a CD,
the unit enters record ready mode after 2 seconds.

If the signal is detected from an MD, the unit enters
record ready mode immediately:

Note that the trigger level is not used here.

or

• the sound level drops below the threshold level for

five seconds

If you set the threshold value so that only high-level
signals trigger recording, remember that this will not
record the start of a piece with a slow fade-in:

Also remember that when recording from an analog
source, the threshold should be set so that it is higher
than the “noise floor” (the base level of hiss, pops
and crackles which may come from an older vinyl
recording, for example). If the “noise floor” is higher
